Two levels toilet eater flushing unit

ABSTRACT

Two levels toilet water flushing unit provides two levels of water flushing, one level to drain smaller amount of water to flush liquid human waste and another level to drain larger amount of water to flush solid human waste. Everybody urinates several times a day and defecates only once a day. If we use the level to drain a large amount of water to flush solid human waste and the level to drain smaller amount of water to flush liquid human waste we can save a very large amount of water to relieve the shortage of water supply in big cities in the States.

THE BACKGROUND OF THE INVENTION

There is shortage of water supply in big cities in the States. One flush of toilet water flushing uses about three gallons of water. This amount of water is designed to flush solid human waste and is too much to flush liquid human waste. The present invented two levels toilet water flushing unit provides one level of toilet water flushing to drain a large amount of water to flush solid human waste and another level of toilet water flushing to drain smaller amount of water to flush liquid human waste. If we use the level to drain smaller amount of water to flush urine we can save a very large amount of water to relieve the shortage of water supply in big cities in the States.

THE BRIEF SUMMARY OF THE INVENTION

An average person urinates several times a day and defecates only once a day. If we use smaller amount of water to flush toilet after urination we can save a very large amount of water to relieve the shortage of water supply in big cities in the States. The present invented two levels toilet water flushing unit is a simple device which can drain a smaller amount of water to flush liquid human waste or a larger amount of water to flush solid human waste.

Numeral 36 of FIGS. 1, 2, 3,4, 5, 6 and 7 is handle node which is built at the left upper quarter of front wing 14. Handle node 36 stops and prevents outer arm 21 of L-shaped handle 19 from moving further upward. Numeral 37 of FIGS. 1, 2, 3, 4, 5, 6 and 7 is blocker node. Blocker node 37 stops and restricts the upward movement of long threaded blocker 29. The level of lower margin of handle node 36 and blocker node 37 is almost at the same level of upper margin of central canal 17. Numeral 38 of FIGS. 5, 6 and 7 is chain. Numeral 39 of FIGS. 5, 6 and 7 is toilet flapper tank ball. Numeral 40 of FIGS. 5, 6 and 7 is pivotal ring of toilet flapper tank ball 39. Numeral 41 of FIGS. 5, 6 and 7 is water drainage hole of toilet water tank 45. Numeral 42 of FIG. 4 is the distance from blocker node 37 to the protruded long threaded blocker 29 which has been protruded (opened) from canal 30 by pushing thumb screw 27 against spring coil 31 toward outer arm 21. Distance 42 is about 1.5/16 inch Numeral 43 of FIG. 4 is the shortest distance from the vertical line which passes through the center of central canal 17 to the vertical line which passes through the center of blocker node 37. Distance 43 is about ½ inch. Numeral 44 of FIG. 4 is the distance from the center of square hole 33 to the center of chain hook 34. Distance 44 is about 8 inches. According to mathematics if ½ inch: 8 inches=1.5/16 inch: X then X is 1.5 inches. So if the protruded (opened) long threaded blocker elevates 1.5/16 inch chain hook 34 will elevates 1.5 inches. Because of the restriction of upward movement of the opened (protruded) long threaded blocker 29 by blocker node 37 if one pushes all the way downward thumb screw 27 to lift up simultaneously the opened (protruded) long threaded blocker 29 and lever 32 the protruded long threaded blocker 29 will be elevated about 1.5/16 inch and chain hook 34 and toilet flapper tank ball 39 will be elevated about 1.5 inches as illustrated in FIG. 6. The elevation of 1.5 inches of toilet flapper tank ball 39 allows small amount of water drain through water drainage hole 41 into toilet to flush liquid human waste and will not induce toilet flapper tank ball 39 to float freely in the water of toilet water tank 45. And once the force of downward pushing of thumb screw 27 is released toilet flapper tank ball 39 will drop immediately to close water drainage hole 41 to stop draining water. Therefore after urination if user first pushes thumb screw 27 inward to open (protrude) threaded blocker 29 and then pushes downward thumb screw 27 all the way to elevate protruded long threaded blocker 29 to hit blocker node 37 for two to three seconds toilet flapper tank ball 39 will be elevated about 1.5 inches high to drain about one gallon of water into toilet to flush human liquid waste and then user releases thumb screw 27 to drop immediately toilet flapper tank ball 39 to close water drainage hole 41. After defecation if user does not push thumb screw 27 inward to open (protrude) long threaded blocker 29 but simply pushes all the way downward thumb screw 27 or outer arm 21 of L-shaped handle 21 to lift up simultaneously chain hook 34, chain 38 and toilet flapper tank ball 39 to more than 2 inches high to induce toilet flapper tank ball 39 to float freely in the water of toilet water tank 45 and then whole tank of water (about 3 gallons) in toilet water tank 45 will drain completely through water drainage hole 41 into toilet to flush solid human waste as illustrated in FIG. 6. Everybody urinates several times a day and defecates only once a day. If we use the level of draining smaller amount of water to flush liquid human waste we can save a very large amount of water to relieve the shortage of water supply in the big cities in the States.
